' ATTORNEY "Patented 1, 1932 UNITED STATES PATENT OFFICE JOSEPH 5058, OFBOSELLE, NEW JERSEY IMHOD 01' MAKING HINGE BUTTS Application filedOctober 6, 1980. Serial No. 486,538.

This invention relates to the method of making hinge butts andparticularly hinge butts having curved hood portions disposed at one endthereof; and the object of the invention is to provide an improvedmethod whereby the fashioning of the blank from which the butt is madeis performed in such manner as to compactly compress the metal at thehood'portion of the hinge so as to form a strong and durable hinge butt;a further object being to fashion the hood portion of the hinge in suchmanner as to reduce the thickness of the wall of the hood adjacent andat the free edge of said hoodand to increase 16 the thickness of theside walls of the hood both with respect to the thickness of the blankfrom which the butt is formed; a further object being to cut the blanksfrom a strip-like workpiece on the bias or diagonally with respect tothe longitudinal and transverse planes of the workpiece to facilitateand simplify the formation of the curved hood portions on said butts; astill further object being to provide an improved method whereby twohinge butts may be fashioned from a single blank, and the hood portionof each butt being disposed at the end portions of the blank and curvedto opposite sides thereof; and with these and other objects in view, the

I invention consists in the method of manufacturing hinge butts which ismore fully hereinafter described and claimed.

The invention is fully disclosed in the following specification, ofwhich the accompanying drawings form a part, in which the separate partsof my improvement are designated by suitable reference characters ineach of theviews, and in which:

Fig. 1 is a longitudinal, sectional view through a hinge butt madeaccording to my invention, the section being on the line 11 of Fig. 2. W

Fig. 2 is a face view of the hinge shown in 5 1.

Fig. 3 shows one method of forming the blanks from which the butts areformed.

Fig. 4 is a perspective view showing the first step in forming theblank. Fig. 5 is a. side and sectional view of a die for completing theformation of the hood porbutt as formed with the dies shown in Fig. 5.

Fig. 8 is a detail view of another form of blank which I employ; and,

Fi 9 is a view similar to Fig. 5 but showing t e dies employed forfashioning a pair gf hinges from a blank such as shown in In Figs. 1 and2 of the drawings, I have shown one form of covered joint hinge or hingebutt which is made according to my improvedmethod, and this buttconsists of an attaching plate portion 10 in which is formed a pluralityof apertures 11 for attaching the butt to a suitable support. At one endof the attaching plate 10 is a substantially semi-circular curved hood12, termi- Dating in a shoulder portion 13 at itsend. Said end of thehood 12 is preferably thinner than the thickness of the attaching plate.The curved hood portion 12 is closed at its opposite ends by wallsforming pintle bearings 14 which are apertured as seen at 15 to receivethe usual pintle pin of the hinge. It will be noted on a considerationof Fig. 2 of the drawings, that the thickness of the bearings 14 isgreater than the thickness of the metal employed in the attaching plate,which result is brought about in accordance with my improved method.

The hinge butt which is shown in Figs. 1 and 2 of the drawings is formedeither from a single blank or a double blank. In Fig. 3 of the drawings,I have illustrated one manner of forming the single blanks and in saidfigure, 16 represents the elongated strip of metal which is cut orstamped diagonally or on the bias to'form two workpiece blanks 10a and10b arranged transversely of the strip 16, it being understood that theoppositely' disposed blanks are cut from said strip" in pairs. in themanner illustrated in said figure, one blank being severed from theother on the line 17, and each blank including laterally extendingcurved-extensions- .8 from which the end walls 14 of the butt areformed.

In dot and dash lines,-I have shown the manner of cutting. the nextadjacent pair of workpiece blanks from the strip 16. It will tion of thebutt in the manner seen in Fig.

4 of the drawings, in which figure, 12a repre-- sents the partiallyformed hood and 14a the partially formed wall members. The workpiece maybe fashioned into the form shown in Fig. 4 by suitable dies, and ifdesired, the

blank may be heated prior to performing this operation. After theworkpieceshown in Fig. 4 has been obtained, it is placed between twodies 19 and 20 shown in Fig. 5 of v the drawings, which completes theformation of the curved hood portion and side walls of the butt.

The die 19 has a beveled wall 19a terminating in a curved socket 196having side walls 190, whereas the die 20 has a beveled wall 20aarranged in parallel relation to the wall 19a when said dies are broughttogether. The upper end of the wall 20a terminates in a raised, roundedknob 20?) adapted to enter the socket19b, at opposite sides of which aresurfaces 200, which control the contour of the outer edges of the walls14 in completing the formation thereof.

Itwill be understood that the workpiece as formed in Fig. 4 of thedrawings, is placed upon the die 20, and as the die 19 moves toward thesame, the workpiece is fashioned to complete the accurate formation ofthe hood 12 and walls 14. The product thus fin ished is shown at 21 inFig. 5 of the drawings as well as in Figs. 6 and 7 of the drawings. Inthe latter figures, it will be noted that around the peripheral edge ofthe side walls 14 and at the free edge of the hood portion 12, therewill be a slight flare of metal indicated at 22 which is trimmed off inthe usual or any desired manner, producing the outlined contour of thebutt as seen in Figs. 1 and 2 of the drawings, after which the pintlepin apertures 15 will be formed in the side walls 14 and the apertures11 will be formed in the attaching plate 10.

It will be noted that by cutting the workpiece blanks 10a-10b from thestock or strip 16 diagonally, the graining of the metal in the resultingworkpieces and especially where the folded corners 23 are to be formed,note Fig. 4- of the drawings, the grains in this part of the workpiecewill be primarily on the bias, thus facilitating the formation of thecorners 23 as well as the hood portion as a whole, preventing crackingand other rupturing of the metal.

At the same time, in compacting the metal or fashioning itinto the formshown in Figs. 5, 6 and 7, andin building up the comparatively thickwalls 14, a very condensed packing or amalgamation of the metal isproduced. Thus, the resulting hinge butt will have by far greaterstrength and durability than any other butt of its kind, constructed inaccordance with old and conventional methods. This result is alsobrought about by virtue of the wedge-like action of the die 19 withrespect to the die 20. It will also be I apparent that by cutting outthe blanks from the stock'in the manner shown in Fig. 3, comparativelylittle waste of metal is experienced, thus effecting a'saving in theamount of scrapping which must be disposed of. It will be understood atthis time that my invention is not necessarily limited to the specificmanner of forming the blanks herein shown and described, nor. to thespecific contour of the resulting product.

In Fig. 8 of the drawings, I have shown at 24 a modified form of blankwhich consists of an elongated strip at the opposite end portions ofwhich are arranged laterally extending, curved projecting members 25,from which the side walls of the hood portions of two hinge butts areadapted to be formed. With this construction, the blank shown in Fig. 8is first fashioned to produce at each end thereof and on opposite sidefaces, the partially formed hood and wall structure similar to thatshown in Fig. 4 of the drawi'ngs, after which the complete blank isarranged between two dies 26 and 27.

The die 26 has a beveled wall 28 which terminates at its upper end in acurved socket 29 and at its lower end in a curved, projecting member 30.The die 27 has a beveled wall 31 parallel to the wall 28 whichterminates at its upper end in a curved, projecting member 32 adapted toenter the socket 29 and terminates at its lower end in a socket 33 inconnection with which the member 30 operates so that a curved hoodportion 34- 34a may be formed at each end of the workpiece, and arrangedat opposite sides thereof in the manner illustrated in Fig. 9 of thedrawings. The central portion 34b of the workpiece joining said hoodportions is severed after completing the formation of the hood to formindependent butts, similar to the butts shown in Figs. 1 and 2 of thedrawings. It is understood that the flared metal around the hoodportionswill be trimmed away as in trimming or removingthe flare shownin Figs. 6 and 7 of the drawings.

In both forms of construction shown, it willbe apparent that the hoodportions are formed at the end of the blank or workpiece,

into the desired'form, and in producing the strength and durability inthe resulting product.

In the several steps of forming the complete hinge buttand especially informing the curved hood portion and the end walls of the hood portion,the blank or workpiece spreferably heated to facilitate the fashionlngof the same into the desired form. It will be understood that I am notnecessarily limited to the particular form and construction of hingebutts herein shown and described, nor to the specific manner of blankingand shaping the same; and various other changes in and modifications ofthe method herein set forth may be made within the ,scope of theappended claims without departing from the spirit of my invention orsacrificing its advantages.

Having fully described my invention, what I claim as new and desire tosecure by Letters Patent, is a i 1.
